-### Branch Policy
-
-
-We have the following branches :
-
- * **dev**
-     All the contributions should be pushed to this branch. If you're making a contribution,
-     you are supposed to make a pull request to _dev_.
-     Please make sure it passes a build check on Travis.
-
-     It is advisable to clone only the development branch using the following command:
-
-     ```
-     git clone -b <branch> <remote_repo>
-     ```
-    
-    With Git 1.7.10 and later, add --single-branch to prevent fetching of all branches. Example, with development branch:
-   
-     ```
-     git clone -b dev --single-branch https://github.com/username/mobile-wallet.git`
-     ```
-
- * **master**
-   The master branch contains all the stable and bug-free working code. The development branch once complete will be merged with this branch.
